mixed method methodology

Science is basically a collection of knowledge and information that is obtained by observation and testing of natural world, in a logical and orderly manner, and its interpretation. Hence, the basis of science is its orderly, step-wise procedure called scientific method. It is a fra..

It is a method by which two or more different crops are grown together in the same soil. A mixed cropping of ragi with pigeon gram replenishes the soil because pigeon gram fixes the atmospheric nitrogen, which goes into the soil in the form of nitrates. From the soil these nitr..

i) Exchange of solvent In this method, a true solution in mixed with an excess of another solvent in which the solute is insoluble but the solvent is miscible. For e.g., a solution of sulphur in alcohol mixed with excess of water results in a colloidal sol of sulphur...

Organic compounds, which are easily soluble in organic solvents but insoluble or immiscible with water forming two separate layers can be easily separated. The aqueous solution of the mixture is mixed with a small quantity of organic solvent in a separating funnel. The separating funnel ..

This method is used for the extraction of lead, zinc, iron, copper, manganese and tin. In this method, the roasted oxide ore is mixed with carbon (charcoal, coal or coke) and a flux, and is heated to a very high temperature in a suitable furnace. Carbon reduces the ox..

Integrated pest management (IPM) refers to techniques of managing the pest by making use of cultural, chemical and biological methods in the form of integrated module (specific to each crop and each situation). IPM techniques include a mix of all available cultural methodsh..

Solvent Extraction consists of separating components of a mixture, which have been dissolved in the same solvent. In order to separate these, the solvent mixture is shaken with another immiscible (that does not mix) solvent. This causes only one of the components to dissolve selectively i..

Sulphur trioxide and water combine very vigorously with a hissing sound. This reaction evolves a lot of heat and produces sulphuric acid. Hence sulphur trioxide is the anhydride of sulphuric acid...

Soil - The word soil is derived from a Latin word solum meaning ground . It is a stratified mixture of inorganic and organic materials, both of which are products of decomposition. Inorganic component of soil i.e. mineral constituents are derived from the soil forming rocks, by fragmentation or wea..
